Director Dumps $411M in NVIDIA; Gates Scoops Up Republic Services

An NVIDIA director and Bill Gates made headlines in early September with two high-profile insider moves that offer a striking contrast in sentiment.

Mark Stevens, an independent director at NVIDIA, filed seven sell transactions totalling $411 million between August 31 and September 2. The sales came in rapid succession across just two trading sessions. Stevens reported the trades publicly on September 2, meaning the market only learned of the activity last month. There is no 10b5-1 disclosure attached to these filings, though the scale and clustering warrant caution. NVIDIA carries a $5.3 trillion market cap. Short interest sits at just 1.3% of free float — bears remain scarce, but a director offloading this much stock commands attention.

On the buying side, Bill Gates has been quietly building a position in Republic Services. Filed disclosures show Gates purchased shares across 65 separate transactions from August 10 through September 2, totalling roughly $927 million. The latest batch — around $66 million over two days — was filed September 3. Republic Services is a waste management company with a $67 billion market cap. The sustained, repeated buying pattern suggests conviction rather than a one-off allocation.

Elsewhere, NVIDIA's General Counsel Tim Teter also sold $6.5 million worth of shares on August 31, filed the same day as Stevens — a cluster of selling from inside the same boardroom.
